Blue Danube Systems, a provider of mobile wireless access solutions that significantly and cost-effectively increase network capacity and enhance quality of service, today announced that it closed $16 million in Series B funding. Previous investor Sequoia Capital and new investor Northgate participated in the round, which also includes a strategic investment by AT&T that will help accelerate early product testing and deployment. To date, Blue Danube has raised a total of $23.7 million in equity financing.

Blue Danube is addressing the explosive growth of mobile data generated from the proliferation of video apps and interconnected devices by making more efficient use of the existing wireless spectrum. The company will use these new funds to accelerate the commercial deployment of a novel radio system, based on its proprietary integrated circuits and software, which enables up to a 10X increase in average cell capacity with existing LTE infrastructure and mobile devices. The technology also empowers mobile service providers to shape capacity to better serve high-demand service areas and mitigate interference zones.

'We have made remarkable progress in delivering first working systems and validating the disruptive potential of our technology,' said Dr. Mark Pinto, CEO of Blue Danube. 'With this level of support from investors, we are confident we will deliver commercial products that provide a 5G experience on today's 4G networks.'
